How to get an input from the user using a Pop-up massege

elnatan 2020-02-20

Hello :smiley:

I'm trying to get a user variable about how much to open the gripper.

How can I generate a pop-up message (at the beginning of the work) that requires the user to enter a number and use it in the gripper width command line?
thanks anyway guys

Hi @elnatan,

The Assignment function might just be able to help you with this.

See my below example code on an E-series robot (will also work on a CB3). To be able to show a prompt, select the Source at the upper right corner to Operator. You may then store this value to a variable and use it on the script command rq_move_and_wait_norm(<0-100 variable>). As you can also see, you can add an operator message so the operator knows what to input in the prompt.

Hope this helps you,

Hello @elnatan
In addition to what Yannik is saying, with this function you will need to enter a number between 0 and 100 %.
100% is the fully closed position and 0% is the fully open position.
You could use a similar command in millimeters (rq_move_and_wait_mm(var_operator)). That way you will be able to enter a value in mm and the gripper will move accordingly.
Note that you will need to calibrate the gripper in the installation tab in order to get the right opening!

Regards.
